I have a prime signature. People have talked about the still point record weight being better than the weight that came with my table. Has any one tried the Mofi record weight? If yes, is it a improvement over my prime signature record weight? Matt, I thought it would be great if you offered a 40th anniversary record weight that comes close to what the still point claims to do by the comments said in this forum and has the 40th anniversary printed on it. Thanks.

I have not tried the MoFi but I own a ton of record weights including the VPI HRX , Stillpoints LP1, Furutech Monza, BDR, TTW Copper, HRS ADH and ADL (the makers of the Mofi). IME and IMHO, the best performing record weight is the Stillpoints. I was never a big fan of the HRS record weight although I very much like their bases, damping discs and isolation footers. The VPI HRX record weight represents excellent value and performance and is a bargain when compared to other record weights.

As garry mentioned, like many of you I have a s#it load of record weights iv'e collected over the years. IMHO the best device bar none is VPI DELUXE STAINLESS STEEL/DELRIN RECORD CLAMP just spin it on add aprox. 1/8 snug turn, drop on my VPI Periphery Outer Ring Clamp (magical) BTW... I paid significantly less than retail for both on Audiogon.

+1 for the Stillpoints, I was using TTW Copperhead and very much prefer Stillpoints. I also prefer it over VPI Delrin Clamp. Don’t get me wrong those all all very good clamps but Stillpoints is my go to now.

I have used the VPI screw down Delrin stainless, VPI hrx, HRS hdl and the Stillpoints. The Stillpoints beat the others by a large margin. It is expensive but we'll worth it considering the sound performance. ➡ Have a look at this ----- viewtopic.php?f=12&t=8502&start=40&hilit=Stillpoint

The Stillpoints LPI functions as a record weight, but to describe it simply as a “record weight” would be something of a misnomer. Unlike conventional record weights and clamps (including those made by VPI and Mofi), the LPI performs a second, unique function, namely, it isolates and dissipates vibrations generated by the table, itself. It is this second function that generally results in significant sonic improvements that conventional record weights and clamps do not. There is a detailed discussion of the benefits of the LPI elsewhere in this Forum. If you’re interested, run a search. Rich

HW did relay and endorse Gary Koh's modification for the HRX center weight. I think Gary would have tried out quite a few center weights and investigated this very thoroughly. In case you missed the post, the mod is to attach three small balls (1/16th of an inch diameter, or 1 mm diameter) under the HRX center weight. The balls are to be made from different materials, and attached at different distances from the center (i.e. not symmetrically).

I have not tried this yet. I have been using the Goldmund Clamp instead of the HRX center weight. The Goldmund Clamp is a huge improvement over the HRX center weight.

Stop Press! I just put three 1 cent coins under the HRX center weight (not symmetrically). There's a big improvement over putting the HRX directly on the LP. It's very close to the Goldmund Clamp in terms of frequency but the Goldmund Clamp seems to have a slight edge when it comes to soundstage and depth.

The results might be different with other coins. How many coins? Dimes/Quarters/Nickels? Krugerrands? And may be there will be a change if the coins were glued.

Just when I think there's nothing left to investigate on my Classic 3, there are a new avenues to explore.

Update: Two coins seem to sound better than three. So the price of this mod has dropped by 33%! I put the two coins a little ways away from spindle. Two coins seem to give the Goldmund Clamp a run for the money.

I couldn't help but try your modification. In MY system 2 dimes work the best. I've only been evaluating for about 45 minutes, but what I found was that there was a definite improvement in soundstage width, and clarity between the instruments. The bass is perhaps a bit less powerful, but certainly the clarity has improved. These are just quick notes....tomorrow is another day. I also found that by positioning a brass floor spike protection disc on the bridge below the 3D arm itself, improves the sound. ...always tinkering.

I have just tried pennies, so far. Better sound when the two pennies are touching the spindle than if they're apart. Definitely up to the Goldmund Clamp, if not better, by a little amount. I can hear the individual words that are sung, and there's a better sense of music phrasing (I hear an interplay of musicians, where one plays something, and that's answered by another musician on the other side of the soundstage) that was just not there before. And yes, I hear better soundstage and separation, too.

I agree, there is a bass cut - but in my book, the bass was a bit too thick and swamped the higher frequencies.
